Planar Fabry-Pérot (FP) ultrasound sensor arrays are capable of high fidelity photoacoustic images. This is due to their ability to sample very densely with small element sizes which exhibit high sensitivity over a very wide bandwidth. However, their planar geometry results in limited-view image artefacts, as well as limiting the visualisation of deeper lying anatomical structures required in some preclinical studies. To address this limitation, a multi-view FP photoacoustic (PA) scanner was developed, enabling full-field detection, thereby overcoming the limited-view restriction while retaining the significant advantages of the FP sensor. This enabled the acquisition of 3-D whole-body PA images of a mouse anatomy with unprecedented quality.
